Direct access to the function by pressing the "battery" button.
Battery voltage, charge current (+ sign) or discharge current (- sign), battery temperature (optional).
If Mains 1 is up - available battery time in the event of a Mains 1 outage.
If Mains 1 is down or outside tolerances - remaining battery time in minutes (real time calculation).
STATIC SWITCH MODUL
◗the available battery time value blinks to attract attention;
◗the battery temperature is displayed only if the "Temperature Monitor" option is installed.
see figure on next page
Note:
Stars appear in the battery backup time display if the battery time estimator function has not been validated by the
